A pesar de tener la teoría correcta, Dirac al principio no encuentra la partícula que tiene carga positiva en su ecuación.

I searched about for some time for some cause that would explain it. I hoped that perhats the Coulomb force between electrons might lead to some relantionship between all the electrons in the negative energy states which would lead to a difference in mass, though I could not see how it could come about. But still, I thought there might be something in the basic idea and so I published it as a theory of electrons and protons, and left it quit unexplained how the protons could have such a different mass from the electrons.

Claro, la única partícula conocida entonces con semejante carga positiva era el protón. Dirac deja escapar el descubrimiento de la antimateria. Pero alguien asoma con otra idea:

This idea was seized upon by Herman Weyl. He said boldly that the holes had to have the same mass as the electrons. Now Weyl is a mathematician. He was not a physicist at all. He was just concerned with the mathematical consequences of an idea, working out what can be deduced from the various symmetries. And this mathematical approach led directly to the conclusion that the holes would have to have the same mass as the electrons. Weyl just published a blunt statement that the holes must have the same mass as the electrons and did not make any comments on the physical implications of this assertion. Perhaps he did not really care what the physical implications were. He was just concerned with achieving consistent mathematics.

Curiosamente, el "más matemático de los físicos", Dirac, descuida la idea de la simetría, traida de nuevo por Weyl.

En el próximo post, veremos aparecer a un físico, continuando las ideas iniciales de Weyl.

Nos leemos!
